The machine that did this circle was amazing, can you imagine how long this would have taken if done by hand the old fashion way? This took a couple of hours via this machine that looked sorta like a tractor but it followed the strings set up the concrete went into the machine and came out in perfect form that is just astonishing to me how could someone think up that kinda thing?
A friend of mine found a picture of the old part at http://library.uco.edu/archives/page-files/image-details.asp?id=2017&sortBy=&iPageNum=22&txt1=&txt2=0 - it'd be fun to have it here to compare the new one with!
